            QUESTION

            Does opening a file in a child process create a separate entry in the system open file table in the kernel?
            Asked 2021-Jun-15 at 23:17

            I understand that after calling fork() the child process inherits the per-process file descriptor table of its parent (pointing to the same system-wide open file tables). Hence, when opening a file in a parent process and then calling fork(), both the child and parent can write to that file without overwriting one another's output (due to a shared offset in the open-file table entry).

            However, suppose that, we call open() on some file after a fork (in both the parent and the child). Will this create a separate entries in the system-wide open file table, with a separate set of offsets and read-write permission flags for the child (despite the fact that it's technically the same file)? I've tried looking this up and I don't seem to be able to find a clear answer.

            I'm asking this mainly since I was playing around with writing to files, and it seems like only one the outputs of the parent and child ends up in the file in the aforementioned situation. This seemed to imply that there are separate entries in the open file table for the two separate open calls, and hence separate offsets, so the slower process overwrites the output of the other process.

            To illustrate this, consider the following code:

            ANSWER

            There is a difference between a file and a file descriptor (FD).

            All processes share the same files. They don't necessarily have access to the same files, and a file is not its name, either; two different processes which open the same name might not actually open the same file, for example if the first file were renamed or unlinked and a new file were associated with the name. But if they do open the same file, it's necessarily shared, and changes will be mutually visible.

            But a file descriptor is not a file. It refers to a file (not a filename, see above), but it also contains other information, including a file position used for and updated by calls to read and write. (You can use "positioned" read and write, pread and pwrite, if you don't want to use the position in the FD.) File descriptors are shared between parent and child processes, and so the file position in the FD is also shared.

            Another thing stored in the file descriptor (in the kernel, where user processes can't get at it) is the list of permitted actions (on Unix, read, write, and/or execute, and possibly others). Permissions are stored in the file directory, not in the file itself, and the requested permissions are copied into the file descriptor when the file is opened (if the permissions are available.) It's possible for a child process to have a different user or group than the parent, particularly if the parent is started with augmented permissions but drops them before spawning the child. A file descriptor for a file opened in this manner still has the same permissions uf it is shared with a child, even if the child would itself be able to open the file.

            Configure Jetty to run a custom filter before filters in war file's web.xml run
            Asked 2021-Jun-15 at 17:41

            I have a third party .war file that I run on a Jetty server. I need to run code for logging purposes before the filters defined in the .war file's deployment descriptor run. The code needs to have access to the incoming request and the response object and to the context of the logger that runs for the app in the war.

            Is there a way to do this in Jetty's xml configuration file? I don't want to touch the war file due to concerns about license.

            I could override the deployment descriptor which would allow me to add custom filters but I believe these would then run after the filters in the war. I could also use a request customizer but that doesn't give me access to the response which I also need to edit.

            I tried adding a handler to a HandlerCollection before the handler with the org.eclipse.jetty.webapp.WebAppContext that runs the war but it doesn't seem that I have access to the web app's logger's context...

            Is there any way to do this? So before the web app's servlet executes run a piece of code that can access the incoming request and the response and the web app's context?

            Option 1:

            To access the raw Request and Response at the various stages of their lifecycles, use the HttpChannel.Listener (make sure you read the javadoc/apidoc to understand what each event means).

            Option 2:

            To add a handler in the WebAppContext, before the Session/Security handling, but after other handlers, use WebAppContext.insertHandler(HandlerWrapper).

            Option 3:

            Create a web-fragment servlet jar that represents your servlet Filter, and add it to the WebAppContext.setExtraClassPath(String), which will be picked up and added to the actual webapp's startup.

            Option 4:

            Create a custom RequestLog implementation (that you add to Server.setRequestLog(RequestLog) that is notified once the request AND response are complete, so you can log the state of the request/log to whatever source you want.

            Option 5:

            Use one of the existing RequestLog implementations to log the details you desire to the console in the format you desire. (Look at the combination of CustomRequestLog and Slf4jRequestLogWriter)

            Errors creating a multithreaded named pipe server with Administrator only access on windows c++
            Asked 2021-Jun-15 at 04:47

            Im trying to create a multithreaded namedpipe server as outlined in the msdn sample here https://docs.microsoft.com/en-us/windows/win32/ipc/multithreaded-pipe-server but Im trying to restrict the namedpipe to access by adminstrators group members only.

            The example works correctly when no SECURITY_ATTRIBUTES structure is specified but when an SA is specified the first call is successful, but following calls to CreateNamedPipe fail as long as the first pipe is listening or communicating with a client. The create call fails, usually with ACCESS_DENIED, but sometimes with error 1305 The revision level is unknown. When the first pipe closes due to client disconnecting the following call will be successful for the next createnamedpipe call but will in turn fail once that pipe has a client.

            I have tried multiple values for the grfInheritance field with no avail. This is my first adventure into explicitly specifying SECURITY so forgive me if I have missed something obvious. Note that in the Function that calls createnamedpipe I create a new SA structure with each create attempt but I have also tried creating one and sharing it outside the create loop.

            Sure, you can use the API "Test Point - Update" to update the outcome of test points.

            For example, I have two test points (id are 22 and 23) are 'Active'.

            I can use this API to update one to be 'Passed' and another one to be 'Failed'.

            Long story short: shader visibility in DX12 is not a bit field, like in Vulkan, so setting the visibility to D3D12_SHADER_VISIBILITY_VERTEX | D3D12_SHADER_VISIBILITY_PIXEL results in the parameter only being visible to the pixel shader. Setting it to D3D12_SHADER_VISIBILITY_ALL solved my problem.

            I am writing a similar task manager app, i have some issues when working with BLoC:

            • First, I create a Page to show all the task that have been added by pressing the FloatingActionButton() below.

            • Next, when the user finished the form by hitting the FlatButton on the top right which is called SAVE, it will be submitted to Firestore, by the _submit() method in the JobForm class.

            • NOTE: I also added some validator to validate the NameForm and the RatePerHourForm so it will show an error when they are null and they worked very well.
            • I used a StreamBuilder() to update my JobPage() ( the first screen ), everywhen the data from Firestore changed.
            • That was a summary of what I am trying to do.

            BUT, when the user press the SAVE button, the Name Field and the ratePerHour Field is always empty even when i called onChanged: , in every TextField() to update them.
